A comprehensive 9-phase smart lighting upgrade spanning urban main roads, community side roads, and pedestrian pathways across Romanian municipalities. CHZ delivered 18,000+ DALI-certified CHZ-ST29 fixtures with FONDA-CITY cloud management - all nine phases passed acceptance with zero rework and 34% energy savings.
Project Background: A 9-Phase Urban-Rural Lighting Transformation
Romania's road infrastructure presents a complex tapestry of lighting environments. From busy urban boulevards in Bucharest and Cluj-Napoca to quiet village lanes in rural counties, each road type has its own illumination requirements, traffic patterns, and maintenance challenges.
The project began as a targeted upgrade in one municipality and expanded over time into a 9-phase program covering multiple cities and rural districts. Each phase brought new roads, new requirements, and new stakeholders - yet all had to operate on the same management platform and use compatible hardware.
The Scale of Deployment
| Total fixtures deployed | 18,000+ units |
| Project phases | 9 consecutive phases |
| Power models used | 20W / 30W / 50W |
| Road types covered | Main roads, side roads, pedestrian paths |
| Control protocol | DALI / DALI-2 dual protocol |
| Networking options | RF wireless + 4G GSM |
| Acceptance rework rate | 0% |
| Management platform | FONDA-CITY (Web + Mobile) |
What makes this project particularly notable is its phased delivery model. Rather than a single large rollout, the project expanded gradually - each phase building on the last, with consistent hardware, software, and commissioning procedures across the entire program. This approach reduced risk, allowed municipal budgets to spread over multiple years, and created a feedback loop where lessons from earlier phases improved later deployments.
Client Challenges
Why off-the-shelf fixtures fell short for Romanian municipal road projects
Complex Road Hierarchy
Three distinct road categories - urban main roads, community side roads, and pedestrian pathways - each requiring different illumination levels, uniformity ratios, and glare control. A single fixture model could not meet all three.
Strict EU Visual Comfort Standards
European road lighting regulations set rigorous standards for flicker-free operation. DALI and DALI-2 certification are effectively prerequisites for municipal tenders across the EU, requiring certified drivers and carefully engineered optics.
Unified IoT Management Across Municipalities
Thousands of fixtures spread across multiple cities needed a single cloud platform for individual addressing, real-time status monitoring, automatic fault detection, and compliance reporting - without administrative silos.
Multi-Protocol Networking Requirements
Romania's infrastructure is uneven - dense urban areas have reliable 4G coverage while remote rural locations often do not. The hardware had to support both RF wireless mesh and 4G GSM on the same fixture platform.
Energy Saving Mandate
Municipal energy efficiency commitments required measurable power consumption reductions through time-based dimming strategies - full power in the evening, reduced output after midnight, minimal overnight lighting.
Multi-Phase Delivery Risk
Nine phases across multiple years create quality and consistency risks. Each batch must match the previous one in fixture performance, control compatibility, commissioning workflow, and documentation.

Scene-Based Optical Design with Pre-Construction Simulation
The foundation of the solution is the CHZ-ST29 series LED street light, offered in three power models precisely matched to the project's road hierarchy:
| Power Model | Road Type | Application Scenario |
|---|---|---|
| 20W | Pedestrian pathways | Sidewalks, park paths, village lanes |
| 30W | Community side roads | Residential streets, parking areas, secondary roads |
| 50W | Urban main roads | City boulevards, arterial roads, high-traffic corridors |
Before production began on each phase, CHZ's engineering team performed multi-round optical simulations using DIALux. Each road segment was modeled based on its actual width, pole spacing, mounting height, and surrounding environment. This pre-construction simulation approach ensured first-time compliance with EN 13201 standards and zero on-site rework.
DALI / DALI-2 Flicker-Free Dimming System
All CHZ-ST29 fixtures are equipped with dual-protocol DALI drivers supporting both DALI and DALI-2 standards. This enables 0-100% stepless, completely flicker-free dimming - fully compliant with EU visual health and road safety standards.
- Dimming range: 0-100% stepless, completely flicker-free at all levels
- Dimming curve: Logarithmic (perceptually linear)
- Driver certification: ENEC, TUV SUD, RoHS
- Energy strategies: Evening peak, midnight dimming, late-night economy, holiday mode
Multi-Protocol IoT Hardware with GPS Positioning
CHZ deployed a layered intelligent control architecture that works equally well in dense urban networks and remote rural locations. Every controller includes built-in GPS positioning for precise geographic tracking on the FONDA-CITY GIS map.
| Hardware | Function | Communication |
|---|---|---|
| LCU-RF | Single-light controller, dimming, status monitoring | RF wireless mesh + GPS |
| LCU-GSM 4G | Single-light control for areas without RF coverage | 4G GSM + GPS |
| FONDA-RTU200Z | Regional data aggregation, group control | RF + Ethernet/4G + GPS |
7-Pin Smart Base + FONDA-CITY Cloud Platform
The entire system is built on a standardized 7-pin intelligent base integrated into every CHZ-ST29 fixture, enabling plug-and-play LCU installation, future expansion for sensors and cameras, and phase-to-phase compatibility. The FONDA-CITY cloud platform is TALQ 2.5.1 certified (Gateway profile), ensuring interoperability with third-party smart city systems.
FONDA-CITY Cloud Platform: The Intelligence Backbone
Six core capabilities that transform a lighting upgrade into smart infrastructure
GIS Map Visualization
Every fixture appears on an interactive map with GPS precision. Operators can switch between 2D street maps and satellite views, zoom to any neighborhood, and see real-time status at a glance - green for normal, red for faults, yellow for offline.
Real-Time Device Management
Individual and batch control: single-fixture dimming and on/off, group control by district or road, project-level all-on/all-off commands, and scheduled tasks for automated dimming schedules and holiday modes.
Instant Alert System
Faults are detected automatically and pushed instantly: fixture failure, driver malfunction, communication failure, overcurrent/overvoltage, cabinet power failure, and leakage current anomalies. Alerts include exact GPS location and recommended action.
Energy Consumption Analytics
Detailed energy data from every fixture generates comprehensive reports: daily/monthly/annual consumption by district, energy savings comparison vs. baseline, lighting rate statistics, and cost analysis with ROI tracking.
Web + Mobile Dual Access
Managers and technicians can access the platform from desktop computers or via the mobile app. Field technicians check fixture status and acknowledge alarms on-site; managers review performance dashboards from anywhere.
OTA Firmware Updates
Firmware upgrades can be pushed remotely to thousands of devices simultaneously - no on-site visits required. This ensures the entire network stays up to date with the latest features, security patches, and protocol improvements.
TALQ 2.5.1 Certification: Interoperability Assurance
The FONDA-CITY gateway holds TALQ Protocol version 2.5.1 certification (Gateway profile, Lighting domain) - verified through 36 test cases. This independent certification ensures standardized API interfaces, interoperability with third-party CMS platforms, and compliance with international smart lighting standards. For European municipalities, TALQ certification means no vendor lock-in.
Measurable Results
Zero rework, 34% energy savings - the numbers speak for themselves
What Zero Rework Actually Means
"Zero rework" sounds like a marketing claim - but in municipal lighting projects, it is extraordinarily rare. Here is what it represents in practical terms:
- No return visits - every fixture passed inspection on first commissioning
- No optical adjustments - pre-construction simulation was accurate enough that no on-site lens or aiming changes were needed
- No control system reconfiguration - DALI dimming, IoT networking, and platform integration all worked correctly from day one
- No schedule delays - each phase was accepted on time, keeping the overall program on track
Operational Improvements
- Reduced maintenance costs - automatic fault detection eliminates routine night patrols
- Faster response times - GPS-precise fault alerts mean crews go directly to the problem fixture
- Data-driven decision making - energy reports and fault trends inform budget planning
- Scalable infrastructure - the 7-pin smart base and TALQ-certified platform support future smart city growth
Key Considerations for European Municipal Projects
+ Best Practices
- Standardize hardware early - pick a fixture family and control architecture that scales from Phase 1 to Phase N
- Invest in pre-construction simulation - days of simulation engineering cost far less than reworking an entire phase
- Choose open-standard certification - TALQ certification ensures interoperability and avoids vendor lock-in
- Plan for mixed connectivity - a dual-protocol approach gives you the right tool for each location
- Build energy savings into the business case - 34% energy reduction is the financial engine that pays back the investment
! Red Flags to Watch For
- "One fixture does it all" claims - if a single model works for all road types, the optical design is compromised
- DALI in name only - many suppliers claim DALI but use uncertified drivers with poor dimming curves
- Proprietary management platforms - no standard protocol support means you are locked in
- No local support presence - smart lighting systems need commissioning and after-sales support. With CHZ's Romanian office (one of 6 overseas offices across Europe, Africa, and South America), support is never far away.
- Single-phase thinking - the real test is whether phases 5, 7, and 9 still work with everything before

Frequently Asked Questions
Q1: What makes the CHZ-ST29 suitable for European municipal projects?
The CHZ-ST29 is specifically designed for the European market with DALI/DALI-2 dual-protocol dimming (fully certified for EU visual comfort standards), ENEC and TUV SUD product certification, and a 7-pin smart base that supports both RF and 4G controllers. The fixture's optical design can be customized per road type through pre-construction simulation, ensuring compliance with EN 13201 standards.
Q2: How does the FONDA-CITY platform handle multi-city management?
FONDA-CITY is built for multi-project, multi-location management. Each municipality can be set up as a separate project with its own device hierarchy, user permissions, and reporting - while a central administrator can view the entire fleet across all locations. The platform's GIS map supports unlimited geographic scaling, and role-based access control ensures each municipality only manages its own fixtures.
Q3: Can existing non-smart LED fixtures be retrofitted with CHZ's control system?
Yes. CHZ's LCU controllers and FONDA-RTU concentrators can be retrofitted to many existing LED fixtures, provided they have compatible dimming interfaces (0-10V, DALI, etc.). However, for optimal performance and full feature compatibility, we recommend the CHZ-ST29 series with its integrated 7-pin smart base for plug-and-play controller installation and complete system interoperability.
Q4: What kind of support does CHZ provide during project commissioning?
CHZ provides end-to-end support including: pre-construction optical simulation and design assistance, factory acceptance testing, on-site commissioning guidance (supported by our local Romanian office), platform setup and configuration, operator training, and post-acceptance technical support. For multi-phase projects, CHZ assigns a dedicated project engineer who stays with the program from Phase 1 through completion.
Q5: How does TALQ certification benefit a municipality?
TALQ (Telecommunication Application for Lighting and Smart City) is an international standard for smart street lighting management systems. TALQ certification means the FONDA-CITY platform uses standardized, open APIs that can interoperate with other TALQ-compliant systems - including third-party CMS platforms, smart city integration layers, and IoT devices. This protects your investment by avoiding vendor lock-in.
